First, I'd like a link to something saying that every advanced stats guy discounts a stat that pretty routinely nails the top guys in the game.

Every statistical model has weaknesses. You're touting PER which is fine, it has some strengths. But any system that says Kyle Korver this year is an average NBA player has some holes(14.89). The guy is having a historic season, and the way he's playing is helping his team to the best record in the league. In the same way that PER can never account for what you do for your teammates on offense in terms of creating space, it can never account for shot prevention and contested shot FG%.

I'll double down. A healthy Kawhi is probably somewhere from 15-8 and in my book a superstar. He's not in the realm of a Lebron or a Chris Paul, or a KD. But he's proven that he can be your best player and you can win a championship.
